Investigating Bubble Wrap as an Insulator Essay Example for Free

Investigating Bubble Wrap as an Insulator Essay Apparatus   Kettle Water   Small Plastic Bag What are we going to do? We are going to experiment for which bubble wrap or bag is the best insulator. We are doing this experiment because to prove my research in the hypothesis. We will test the big bubble wrap, small bubble wrap, a plastic bag and just the steel can. To extend the experiment we will test the bubbles facing inwards and outwards of the steel can. This will be used for the big bubble wrap and small bubble wrap. 1. First we will boil up some water in a kettle. 2. Then, we will measure the 140ml in a measuring cylinder. This is because we wont to know how easily heat energy can escape through the can. 3. We shall pour the 140ml of hot water on the steel can. 4. We will put a plastic lid on top of the can. A thermometer will be put through a pierced hole into the middle of the plastic lid. 5. Later we will measure the temperature. 6. As soon as the temperature falls to 84 degree, we will start the timing. 7. We will record the temperature every minute for 10 minutes. After ten minutes the experiment will be done. 8. We will repeat the experiment to find an average temperature for every minute. 9. Finally we well repeat this experiment for the big bubble wrap facing in and out of the can, the small bubble wrap facing in and out of the can and the plastic bag around the steel can. We have chosen to start every experiment at 84 degrees because we think the water may not reach temperatures as high as 90 degrees. For a fair test we will measure the temperature at every minute to make equal spacing of time between each reading of time. ANALYSIS Apparatus Small Plastic Bag Method In my experiment I kept many of the things I was going to do, the same. But after finding a couple of difficulties in the experiment I had to alter a couple of things. They were:    The process of measuring the hot water. I found out that the temperature of the water decreased rapidly so I could not start the experiment at 84 degrees. So I changed the process of measuring the water. Instead of measuring the water after boiling it up, I measured the water before boiling it up. This meant that I had to put 5ml of extra water in the kettle because a tiny bit of the water would have been evaporated.   Inserting more water into the steel can. I found out that the steel can was not being filled to the top. This meant that the air between the lid and water had been transferring heat energy by convection. I stopped this by adding 10 extra millilitres of water into the steel can. Conclusion In my results table I have observed that the big bubble wrap was the best insulator. The small bubble wrap was a worse insulator than the big bubble wrap and although the plastic bag was the worst insulator, it was the best insulator. The results of the experiment with no covering on the steel can did not fit the graph. This is because the graph showed that the experiment with no covering on the steel can was a good insulator. I would have thought that no covering on the steel can would have helped the heat energy escape. The only explanation for why the graph showed that the experiment was a good insulator is that a big, thick object would have been near the steel can preventing from escaping so easily. In my prediction, I said that the big bubble wrap would be the best insulator. This is because there is a lot gas in each bubble preventing heat energy from escaping so easily. The atoms in a gas are little and very spread out which makes the vibration of one atom to another very hard. I also said that the plastic bag was a good conductor because the heat energy only had go through the steel can and plastic bag. There was not much gas between the steel can and plastic bag together because the plastic bag was close to the steel can. Heat energy can go through a solid easily by conduction because the atoms are close together making the vibrating of each atom easy. This theory has been proved by my results and graph. I decided to record the temperature at every minute in each the experiment, because then I would have a wide range of results of the temperature decreasing. EVALUATION There were some things that were not fair which made the experiment go wrong a little. They were:- 1. The reading of the temperature. Sometimes I would not reading the temperature because the marks on the thermometer were squashed together so I could not read the numbers so easily. If I had a high-tech piece of equipment (e. g. a computer) then I could connect a thermometer to the computer and just read the temperature off the computer. 2. The reading of the temperature APPROXIMATELY every minute. Most of the time I could not read the temperature exactly every minute. Sometimes I was reading the temperature before the minute and sometimes after the minute. This effected my results because some results read the same and some had a big decrease (like the point at the orange circle). I could get solve this problem by also using a computer and connecting a stopwatch to it so the temperature could be given at exactly every minute. 3. The rounding off of a number after being read. Many of the numbers that I read were not whole numbers. So I had to result to rounding the number off. This effected my results because again some results read the same and some had a big decrease. If the thermometer had smaller marks telling you the numbers then I could have precise results. We could result to using a computer. I was not happy with my results with my results for no covering at 1 minute (marked orange circle) because of all the reasons above. These reasons are why my graph a bit out of shape. Although my graph was not accurate, my results were reliable to prove my prediction. My results clearly show that the big bubble wrap was the best insulator (and a bad conductor) and the experiment with the bag was the worst insulator (and a good conductor). I could make my results better by repeating the whole experiment again but this time using all the suggested I have given. If I were to do this then I would get the accurate results and prove that the experiment without covering would be the worst insulator. I would do the experiment three or four times to get a better and more reliable average. My results are not sufficient to prove my conclusion. I think I would have to do the experiment with no covering again to at least make my conclusion right.

Charlemagne, or Charles the Great, King of the Franks :: Medieval Europe European History

Charlemagne, or Charles the Great, King of the Franks Charlemagne, or Charles the Great, King of the Franks (742-814), was a strong leader who unified Western Europe through military power and the blessing of the Church. His belief in the need for education among the Frankish people was to bring about religious, political, and educational reforms that would change the history of Europe. Charlemagne was born in 742 at Aachen, the son of Pepin(or Pippin) the Short and grandson of Charles Martel. His grandfather, Charles, had begun the process of unifying western Europe, in the belief that all people should be Christian. Charlemagne's father, Pepin, continued this process throughout his rule and passed his beliefs on to Charlemagne. All three, in addition to the political unification, believed that the church should be reformed and reorganized under the Pope, which helped their rise to power as the Carolingian Dynasty. (Holmes 74) Upon Pepin's death in 768, Charlemagne and his brother, Carloman, each inherited half of the Frankish kingdom. Pepin, in the Merovingian tradition of the time, split his kingdom between his two sons. Three years later Carloman died and Charlemagne took control of the entire kingdom. He inherited great wealth and a powerful army, built by his father and grandfather. Charlemagne used the army and his own skillful planning to more than double the size of the Frankish Kingdom. (Halsall 15) The world of Charlemagne was a heathen one, with many warring tribes or kingdoms. Many of these tribes were conquered by Charlemagne, among them the Aquitanians, the Lombards, the Saxons, the Bretons, the Bavarians, the Huns, and the Danes. The longest of these battles was against the Saxons, lasting thirty-three years. Charlemagne actually defeated them many times, but due to their faithlessness and their propensity to return to their pagan lifestyle, the Saxons lost many lives in the prolonged battles with the Franks. With each conquest the Frankish kingdom grew, and with growth came additional power and responsibility for Charlemagne. In each area of Europe that was taken over by Charlemagne, he removed the leaders if they would not convert to Christianity and appointed new ones, usually someone with high position in the Church. Those people who refused to convert or be baptized in the church were put to death. (Holmes 75) The Church played a vital role in the kingdom of Charlemagne. It gave a sense of stability to Charlemagne's rule, and he in turn provided stability in the Church. The people conquered by Charlemagne, after being converted to Christianity, were taught through the Bible a unified code of right and wrong. It was necessary for the Church to play a role in this education of the people,

Reintroduce Children’s ASPIRIN

Given the respective scenarios and the projections described in the exhibits for each option, evaluate and choose the alternative that best optimizes Bayer’s prevention and children’s business. Explain. Upon reading the two options that have come up, the best alternative would be choosing the second option: Reintroduce Children's ASPIRIN worldwide as a prevention product and rename it under the brand ASPIRIN 100 ®. Figure 2 (See below) summarized that this option appears to have more benefits than the first option given.Although venturing into this option would require repackaging, relabeling, and reindicating the brand and it might accelerate the cannibalization of Pharma's sales, reintroducing the product could attract new users from competitive brands. As Joachim Zander analyzed the two scenarios under when they reintroduce their product: â€Å"Under the first scenario, we essentially create attention for ourselves and the market reacts. As a result, Pharma's high -end product, CardioASPIRIN ® , loses 10% of its sales due to our cheaper alternative.However, we also appropriate incremental sales of 10% from the competition. Beyond that, by keeping the product on the market, though in a new form, we are able to keep 20% of the children's ASPIRIN customers. Under the second scenario, I envision that the market does the opposite and reacts very little to our product change. Thus, Pharma doesn't lose any volume, and Consumer Care is unable to gain any incremental volume from the competition. Either way, we still keep 20% of the children's ASPIRIN customers.† Comparing Exhibit 6 with Exhibits 7A and 7B, the forecast losses in Option 1 will be substantially greater given the Middle and Worst Case Scenarios than what is featured in losses in Option 2. Although in the Best Case Scenario in Option 1 could appear to be advantageous, assuming that scenario to happen would be faulty. Also, as emphasized in Exhibit 5, although the sales of children ’s aspirin is declining, its margin against the Prevention CardioASPIRIN ® is still significantly higher.Keeping their seasoned and most valued customers who give them more profits will be the optimal approach. Thus, the win-win solution would be Option 2 because either way 20 percent of the children’s aspirin customers will be maintained. This business decision will be less damaging to the company, either best or worse case happens. 2. ) Do you agree with quantitative assumptions used to develop the forecasts? Why or Why not? Yes, I agree.In order to come up with the best decision, managers must make a number of educated assumptions about future trends and events and modify those assumptions once new information becomes available. Quantitative forecasts are typically based on historical data or tests and which involve complex statistical computations, which the Bayer Aspirin Case presented to represent the financial outcomes of the two options. Although quantitative forecasting is not foolproof, it is a valuable tool that enable managers to fill in the unknown variables that inevitably crop up in the planning process.For instance, the case study obtained the trend from 1994 to 1998 to formulate the outcomes of the trends in 1999 to 2003. The results they obtained indicated that prevention customers had been rapidly replacing children customers over the five years from 1994 through 1998. Forecast indicated by 2003 that approximately 27% of Children’s ASPIRIN sales would be for children and 73% for prevention customers, effectively reversing the 80% / 20% split, respectively, from 1994.Upon seeing the trends, Zander and Merker had the ability to conclude that Children’s ASPIRIN was naturally evolving into a low-cost, low-dosage prevention product. And it looked as if the combination of the rapid growth in the prevention market and the decline of the children’s market would be the death of the Children’s ASPIRIN brand. Of course, these are just assumptions and these could be wrong but at least the present trends could spell a lot with what will happen in the future.

Euthanasia is a painless death, some may say euthanasia is a undeviating act for taking a life through prescription drugs. A patient that has a short expand of life can address such an issue with their healthcare provider. Counseling can be provided before the final decision is made by doctor and the patient. Don’t waste time! Our writers will create an original "What is Euthanasia?" essay for you Create order At anytime the patient reserves the right to with draw from the process. The patient however must have good reason for the process before a doctor will approve such a request. Written documentation can be obtained from the ethics of medical and research on the website, through his/her doctors office. If the doctor has agreeded with patient that this is the best option both patient and doctor will be protected through legal binding documents and laws of that state. The patient also has the right to request family, friends and spouses to be present during the time of this process. This type of euthanasia can be considered as a voluntary act. Identify and describe laws regarding euthanasia in your state. The extermination of life is restricted in Louisiana and all through the whole United States. Louisiana Right to Lifes Center for Medical Ethics systematized into law the Louisianas Natural Death Act for consenting or denying medicinal treatment which currently explicitly peruses: Nothing in this Part will be translated to excuse, approve, or favor leniency slaughtering or killing or to allow any agreed or purposeful act or oversight to end life other than to allow the characteristic procedure of passing on (RS 40:1299.58.10). Explain a recent case about euthanasia and its outcome. Mr. Noel Conway is a 67 yr old termally ill man want to exercise the law on assisted death, so that he may go in a more dignified way. The request was presented and denied three times in court. Mr.Conway revealed that the Suicide Act of 1961 contradicts article 8 in reguards to human life and privacy to the judges. However to no avail the judges did not move on the act of euthanasia. Mr. Conway plead his case on the legal matter and he stated that he will continue to come before the courts until his request is granted. Mr. Conway has a breathing machine that carries every breath for him. Even though he is dieseased ridden, his only option is to smother to death by removing the breathing tubes in his nostrals. Mr. Conway feels as if his rights as a human was not only granted but disreguarded. Mr. Conway is not expected to live pass another year. Maybe if he had presented his request under six months of life while in a stable frame of mind. He might have had a better chance at dieing a peaceful death and saying goodbye to love ones at his own leisure. Another reason why his request was denied is because he was depending upon his physician to assist with this act. However the laws is not in favor of act and is strictly prohibited. Based upon what you have read, give your opinion on euthanasia, and support your argument I am against euthanasia because it is morally wrong. To be able to disregard human life due to illnesses and diseases strips away the value of mankind. This could also start a trend in the medical field for using euthanasia as treatment instead of a cure. For religious reasons this takes life from the hands of a higher spiritual power.
